We are offering one component polyurethane sealant is a kind of sealant that is one-component and cures at room temperature. The paste state makes it be squeezed out to operation. One-component polyurethane sealant cures by absorbing the moisture in the air. And it reacts with active group in the surface to play the adhesion role. It is not saggy, so it will not flow when used in vertical joints. It can adhere on metal, rubber, wood, cement, ceramic and glass. It has two functions: sealing and waterproofing. And one-component polyurethane sealant can be divided into two kinds according to the reaction encountering water: water-swelling sealant and no swelling sealant.Features:one component, easy to use and can construct with a standard caulking gun.Excellent waterproof ability.Good aging resistance. Its weight change ratio is very low. And there are urethane linking chains in its structure. So the expansion units will not lose during using. Its using life can exceed 100 years at room temperature.High bonding strength and outstanding sealing capability. It can bond on the concrete surface firmly whether the surface is damp, smooth or tough. What's more, it has good adhesion capability with metal, rubber, wood, cement parts, ceramic, glass and so on.No sagging. Used in sealing vertical and the top joints not flowing.Environmentally friendly. It is resistant to many chemicals, such as hydrochloric acid, salt water, sodium carbonate and potassium hydroxide. It can contact with drinking water. It is safe and nontoxic.Shelf life: 12 months in original unopened package, stored in dry and cool environment, and keep the temperature between +5c to +25c.Color: black, white, gray or customized.

We are offering two component polyurethane sealant.Polyurethane rubber and the prepolymer of polyurethane are the main components of polyurethane sealant. Polyurethane sealant can be divided into three kinds: heating curing polyurethane sealant, room temperature vulcanized polyurethane sealant and hot melt polyurethane sealant. And the room temperature vulcanized polyurethane sealant is divided into two kinds: one-component polyurethane and two-component polyurethane sealant. Two-component polyurethane sealant (double-component polyurethane sealant) is mainly used in the secondary sealing of hollow glass, and one-component polyurethane sealant is mainly used in the sealing of automobile.Two-component polyurethane sealant includes a component and b component, and the two components react to cure. A component is milk white or light yellow viscous prepolymer of polyurethane. B component is black paste or liquid that is produced by curing agent and auxiliaries mixed and dehydrated. It has certain elasticity and cohesiveness after curing.The classification of two-component polyurethane sealant:it can be divided into two kinds according to the flowability: non-slumping and self-leveling.It can be divided into two kinds according to the movement ability: 25 and 20.It can be divided into two kinds according to the tensile modulus: high modulus (hm) and low modulus (lm).
