The peeling protective coating is a liquid protective coating made of waterborne polyurethane, which can be sprayed on the surface of automobiles, furniture, electrical appliances and other objects as a protective coating.It has good formativity, can in complex shape surface to form a layer of continuous, uniform stick, strength, transparent protective coating, no need baking, room temperature drying quickly, without harmful gas such as formaldehyde, benzene, ammonia release, after dry film, easy from the object of the zhang jie, no temperature requirements, without water and solvent cleaning, stripping of film can be recycling use, the coating resistant to sunlight exposure, Resistant to water, oil, alkali, salt liquid, dilute acid function, coating temperature dependence is small.Production and construction technology is simple, applicability is wide without environmental pollution of environmental protection paint. Peeling coating has strong water resistance, oil resistance, corrosion resistance and insulation, spraying on the surface of the object, that is, the formation of a layer of peeling film, through the film of the object's effective isolation, to prevent dirt, rust, acid and alkali, abrasion and a tear that is the new state of mind.

Technical parameters: Color: Blue or white Viscosity: can be adjusted according to customer's actual operation needs Drying time (room temperature) : table dry 20min dry 2h dry (60℃) 7min Flexibility: good temperature resistance: 160℃ for 24 hours Acid resistance: 25%H2SO4 24 hours alkali resistance: 40%NaOH 24 hours Salt resistance: 30%NaCl for 24 hours

Product character Appearance：Milky white or dark blue gelatinous liquid Solid content : ≥41% PH: 7.0 to 8.0 Viscosity: 1200 ~ 1800 (MPA.s) Performance characteristic 1.Peelable coating is made of waterborne polyurethane, weather resistance 24 months, ice resistance, acid and alkali resistance. 2.Water based formula, odorless and tasteless, free of heavy metals and halogen, in line with SGS and RoHs standards. 3.The protection cycle can be more than 2 years in natural environment. It can be used on metal surface and painted surface. 4.The membrane body after tearing is removed without residue. Application 1.Apply the product to metal, glass, ceramic, paint, plastic and other surfaces, and form film after natural drying. 2.The film body has strong toughness, transparency, tear, anti-scratch, anti-wear, anti-dust and cleaning protection. 3.The film body has good solvent resistance, oil resistance, rain washing resistance, long time high temperature exposure. 4.The film body is not sticky in summer, the film body is not brittle in winter, and there is no residual glue after cleaning. 5.Especially suitable for long time weather protection in indoor and outdoor natural environment 6.Typical users such as: glass curtain wall, aluminum alloy doors and Windows, stainless steel parts, automobile transportation protection, elevator engineering, glass fiber reinforced plastic products, metal rust prevention, large construction machinery, paint room block protection. Application method Open it and use it. peelable paint is sprayed by electric spraying machine or coated with wool brush. If spraying is used, it is recommended to add about 5% ~ 10% water to the tear film latex to dilute, stir evenly and then spray. Spraying method is similar to latex paint spraying, which is naturally dry and can be torn off by finger when not needed. The drying film formation time is as follows: Temperature 20℃ ~ 30℃ for about 3 ~ 5 hours Temperature 30℃ ~ 40℃ for about 1 ~ 1.5 hours The temperature ranges from 50℃ to 60℃ for about 15 minutes Points for attention: This product meets the requirements of environmental protection, the membrane body is non-toxic to the human body can be skin contact. Please confirm the sample before use in large quantities. Packaging and Storage: 25Kg plastic bucket airtight packaging. This product can be stored for one year. Please store in a cool and dry place at 5-35℃ and keep sealed away from direct sunlight. This product is non-dangerous goods transport. Pay attention to frost protection.

Automobile seal strip is one of the important parts of the automobile, widely used in doors, Windows, body, seats, sunroof, engine case and trunk and other parts, with waterproof, sealing, sound insulation, dust, antifreeze, shock absorption, heat preservation and energy saving important role.The rubber flocking seal occupies a very important position in the automobile seal system. The rubber flocking seal includes the door and window glass guide seal and waist seal. In addition to the basic sealing and reducing the wind noise function, it also provides the guide rail and support for the glass lifting. The choice of flocking glue should first test that the glue matrix and sealing strip elastomer have good infiltration. Flocking glue is divided into solvent-based glue and water-based glue, and can be divided into single component and double component according to the curing reaction mechanism.In the actual production of rubber flocking seal strips, polyurethane as the matrix xylene or ketone as the solvent is usually selected as a single component adhesive, but this solvent based flocking glue price is high, and has volatile organic solvent, serious harm to the health of the construction personnel and users. It is also a fire hazard when baked at high temperatures. Waterborne polyurethane flocking glue, instead of the previous use of solvent flocking glue, non-toxic environmental protection, is a new generation of green products.

What is a coupling agent? Coupling agent is a class of substances with amphoteric structure, a part of their molecules coupling agent is a class of substances with amphoteric structure, a part of their molecules can be divided into groups and inorganic surface chemical groups reaction, forming chemical bonds; The groups can react with the chemical groups on the inorganic surface to form chemical bonds;Another part of the group has the nature of organic matter. But another part of the group with organic molecules has the nature of organic matter, can react with organic molecules or produce strong intermolecular action, which will be two totally chemical reaction or produce strong intermolecular action, which the nature of the two kinds of disparate materials tightly together, Improve the inorganic filler in the polymer matrix firmly combined with different materials, improve the dispersion of inorganic filler in the polymer matrix, improve the mechanical properties and usability of the polymer material in the dispersion of the polymer material, improve the mechanical properties and serviceability of the polymer material.
