Polyurethane Adhesive for Sandwich BoardPolyurethane Adhesive for Sandwich Board
DQT-508
Introduction
Polyurethane Adhesive for Sandwich Panels is two components foaming type PU adhesive, with excellent adhesive property, widely used for binding sandwich boards for industrial plants and cold rooms etc. The main characteristics are as follows,
l With absorption and adhesion to different kinds of materials, not only bond porous materials, but also smooth surface materials.
l Excellent cohesive property, formula with good tolerance, which can meet different cohesive properties and technology requirements, the low temperature performance is better than other kinds of adhesive.
l No byproduct produced while cure, will not cause defect on the cohesive surface.
l Excellent mechanical performances, with nice ageing resistance, shock resistance and oil resistance etc.

Attentions
Colored steel plates need to be smooth surface, dry and no greasy dirt and dust. PS foam plates should be same thickness, even texture, the thickness difference is below 1%, surface should be dry, no greasy dirt or dust. If can't meet the requirement above, the cohesive performance will be affected.
Protection
Using the product should comply with normal standards of industrial hygiene, labor protection products need to wear well, to avoid skin, eye contact with materials, when the skin was stained, the application of soap and plenty of water to flush out; If contact with eyes, then the application of low-pressure flow of clean water wash away, if the persistent discomfort, should be invited to the medical treatment.
