Pressure sensitive adhesive in addition to the adhesive, but also to add adhesive and other auxiliary substances.
1.The adhesive of the pressure sensitive adhesive has rubber or synthetic resin and other materials, its role is to give the adhesive layer enough cohesion strength and adhesion, the dosage is 30%-50%.
2.Viscosifier. Viscosifier rosin and its derivatives, petroleum resin, etc., its role is to increase the adhesive layer adhesion. Its dosage is 20% to 40%.
3.Plasticizer. The plasticizer used is the plasticizer used for general plastic processing, and its role is to increase the fast viscosity of the adhesive layer. Its dosage is 0-10%.
4.Anti-aging agent. General rubber, plastic antiaging agent can be used, the role is to improve the service life, the dosage is 0-2%.
5. Packing. The filler used is the general plastic filler, the effect is to improve the cohesion strength of the rubber layer, reduce the cost, the dosage is 0-40%. In addition, some pressure sensitive adhesive, also need to add viscosity regulator, vulcanizing agent and solvent.
