Product introduction
This adhesive is mainly polymerised by polyisocyanate (including diisocyanic acid) and polyols and no byproduct during the reaction. As a result, the volume contraction is smaller, and the internal stress produced after the curing of the rubber layer is smaller. There is a amount of aminoester group in the molecular chain of this adhesive, besides, its molecular chains can also contain the polar groups such as ester bonds, ether bonds, urea kettles, and allophanate bonds and others.
Product advantages
1. Excellent adhesion strength, peeling strength and shear strength are very strong even in low temperature environment.
2. Good abrasion resistance and high adhesion. Because of the polar and active carbamate and isocyanate groups in the adhesive chain, it exerts good bonding strength with many materials, such as metals, ceramics, glass, rubber, wood, cement and part of plastic.
3. Good chemicals resistance, and excellent acid and alkali resistance.
4. Good vibration resistance and fatigue resistance. The interconnection points of this product are longer than those of other thermosetting adhesives, can withstand repeated loads, especially suitable for flexible material.
