Mechanical Surface Polyurea
Qtech-404 can produce extremely hard films at all thicknesses; it can be applied to all locations and any properly prepared substrate. Labour protection measures:In the process of using this product, we must wear work clothes, goggles, gloves, gas masks and other labor insurance products.Qtech-409 armor chassis impact-proof and friction-proof polyurea material is a semi-prepolymer with NCO-terminated group in component A and a two-component elastomer material with amino-terminated polyether, amine chain extender and additives in component B. Qtech-409 can be used alone or in combination with other materials for military armor, charge boats, friction-proof sparks and impact-proof coatings, linings and wear-resistant coatings between stones and metals, minerals and metals, metals and metals, etc. Qtech-409 can form hard coatings with different thicknesses, and can be applied to various occasions and suitable substrates. Qtech-409 is insensitive to moisture and humidity, and can be used in harsh environmental conditions.
