polyurethane construction sealant CS-A4 is a kind of high-powered,elastic after cured,well-sealed one-component
polyurethane building sealant. It reacts with air and solidifies to form
a permanent hyperelastic materials. CS-A4 is in strengthened structure,
widely used in bond and sealing of construction material.

Construction attentions:
1.Carefully check relative identifier of sealants products.
2.Remove all kinds of oil and dirt,keep jointing surface cleaning&dry.
3.Use relative cleaning activator handling agents or primer selectively.
4.Use manual or pneumatic gun paint,repid adhesive in surface dry time.
5.The best construction temperature 5-40C,RH between 65%-75%.
6.Uncured CS-1001 can be removed from tool or equipment,cured can only be removed by mechanical mean.Use industrial handrub immediately if you hand or skin gum on,not solvents.
