Anhui Sinograce Chemical Co., Ltd. participated in the twenty-third China International composite materials industry technology exhibition in from September 6th to 8th. At the exhibition, we mainly display glass fiber positioning adhesive, self viscose and other hot products. Before the exhibition, we made an appointment with the Indonesian customers in advance. At the exhibition, we carried out a deep discussion on water-based glue, water-borne polyurethane wood paint, metal paint and special resin for labor protection gloves. In addition, several other customers at the exhibition have also taken a great interest in our products, and two customers went straight to the factory and expressed satisfaction with our production line and service. Anhui Sinograce chemical's products by the vast number of new and old customers. Many customers on-site detailed consultation, hope that through this opportunity to carry out in-depth cooperation. Through this exhibition, we reached a cooperation agreement or intention of many customers to carry out friendly exchanges, made many new friends, understand the waterborne coatings and adhesives market new, open international vision, brings great confidence and opportunities for our development in the future.

The rubber pressure-sensitive adhesive in addition to the main components of rubber, while adding a thickening resin, plasticizers and so on. The rubber type pressure-sensitive adhesive is made of rubber elastomer, thickener, softener, antioxidant and other components dissolved in the preparation of solvent.In addition to resin, resin pressure-sensitive adhesive must also add to defoamer.Wetting agents and so on.  Among the resins, polyacrylate is currently the most widely used, it is generally used for sealing tape, labels, stickers and women's products. Silicone and other resin-based pressure-sensitive adhesive are composed of silicone resin and silicone rubber mixture of pressure-sensitive adhesive, with high temperature and anti-aging properties, is a very important special pressure-sensitive adhesive.

How to judge the quality of waterborne pressure sensitive adhesive？ Pressure-sensitive adhesive quality of good or bad, generally from the drying speed, viscosity, adhesive strength, solid content and PH value and other aspects to measure. 1, pressure-sensitive adhesive drying speed When buying pressure-sensitive adhesive, it is necessary to measure whether the drying speed matches the bonding process. The general manual bonding process is slow, requires a long initial dry time; Machine bonding process is very fast, requiring short initial drying time. For the initial dry time, the vast majority of cases require the sooner the better, so as soon as possible into the next road process. 2, the viscosity of pressure-sensitive adhesive Viscosity is the most important factor affecting the quality of adhesives. If the viscosity is too large, the coating is thick, consumption of plastic large, slow drying, but also affect the adhesive on the surface of the sticky material wetting and infiltration, and thus directly affect the adhesive strength; if the viscosity is too small, The coating is thin, too fast drying, prone to poor adhesion and other issues. 3, the adhesive strength of pressure-sensitive adhesive Pressure-sensitive adhesive must have sufficient adhesive strength to ensure the normal use of the object after bonding. You can ripped two sticky materials along the adhesive interface, to determine whether the adhesive strength is qualified. If it is found that the material is damaged after tearing, it is proved that the adhesive strength is sufficient. If only the adhesive interface is separated, it indicates that the strength is insufficient. 4, the pressure-sensitive adhesive solid content Solid content is also one of the important factors affecting the quality of pressure-sensitive adhesive. If the pressure-sensitive adhesive content is higher, then it has less water, the stronger the adhesion, the faster the drying speed. General pressure-sensitive adhesive content of 55% ± 1. 5. The pH of the pressure sensitive adhesive Synthetic resin adhesive mostly weak acid, the bonding process will not have a negative impact. But the water glass and starch adhesives alkaline high alkaline high will not only on the operating personnel and equipment corrosion, and sometimes corrosion of sticky objects, the formation of the appearance of the mark. Therefore,  the purchase of adhesives to consider the impact of pH on the product.

China's adhesive industry in recent years has made relatively large progress, the specific performance are in the following areas: (1) New products continue to emerge. Some modified type, knot type, copolymer blending type and special type of adhesive have been developed, some have realized the industrialization. Such as polyurethane modified polyvinyl acetate emulsion, frost-resistant white latex, double-horse modified epoxy conductive adhesive, silicone modified epoxy resin and so on. These products have a lot of excellent performance, not only to meet the various needs, but also improve the grade of China's adhesive products, replacing some of the imports. (2) Production technology to accelerate. China's adhesive production technology has made great progress. The new production technology represented by radiation, UV solidification and interpenetration network, In improving product performance, improve the quality of products, has played a very important role in improving the performance and quality of products. (3) Application areas continue to widen. At present, the application of adhesives has been infiltrated into the various sectors of the national economy. Such as clothing, light industry, machinery manufacturing, aerospace, electronic appliances, transportation, health, e-mail, warehousing and other fields, has  becoming indispensable technology in industrial production. In the automotive industry, the application of adhesives is for the simple, reliable and cost-effective process. Used for metal, plastic, fabric, glass, rubber itself or interconnected and painted surface structure connected, fixed and sealed.
