SPUA-D50A/B Two Component Spray Polyurea
SPUA-D50A/B two-component spray polyurea
Description
Spray polyurea waterproof coating is a spray type two components elastic coating composed of components A and B. Component A is a semi prepolymer prepared by the reaction of isocyanate with oligomer Diol or ternary alcohol, and component B is composed of amino terminated resin, hydroxyl terminated resin, amine chain extender, pigment and additives. Elastic polyurea material formed through on-site spraying with professional equipment. This product has excellent mechanical properties, medium resistance, outdoor aging resistance, and excellent adhesion.
Applications(Non-exposed type)
Suitable for high hardness for pickup lining, mine wear mechanical lining and wear deck.
Characteristics
- The addition of urea group polymer with crosslinker and terminal amino polyols can significantly improve the material performance.
- Suitable for soaking and waterproof occasions.
- Does not contain harmful substances, and the paint film is non-toxic.
- Strong bonding force with a variety of materials (including metals, ceramics and composites).
