Qtech-113 Polyurea Recoat Plyadhesive




Qtech-113 Polyurea Recoat Plyadhesive

Production Description
Qtech-113 Polyurea plyadhesive is independently developed by Qingdao Shamu International Trade Co., Ltd. and it is a china patent technology (No: 200910020530.1). It is low solvent, ambient moisture and temperature insensitive, structural non-sag plyadhesive material. The system consists of two components A (resin) and B (curing agent). It is formulated to apply in pre-polyurea and recoating polyurea or other coatings, liners and so on. Qtech-113 provides the high adhesion prior to recoat polyurea to polyurea or other coatings. Qtech-113 is polyurethane based two component, high solids, liquid applied recoated plyadhesive material with unique adhesion characteristics.
1.  Fast cure, short down time.
2.  High modulus, high strength, structural gel adhesive.
3.  Non-sag gel for vertical and overhead applications.
4.  Creamy viscous consistency for easy recoating of pre-coatings.
5.  Excellent adhesion to most difficult surface.
6.  Easy 2:1 mix ratio(A:B) and consult us.
7.  Application at a wide of temperature range.
8.  Remains flexible in wide range of temperatures.
9.  Chemical attack resistance.
Recommended Uses
•  Recoat polyurea to pre polyurea such as Qtech serial products.
•  Recoat polyurea to pre coatings.
•  Adhesive for metal, wood, polyurethane form, plastic and so on.

Freight Classification
Coating Solution Non-Flammable Liquid .
Surface Preparation
Profile the pre polyurea or other coatings surface, the surface must be clean and sound. It may be free of standing water. Remove dust, laitance, grease, curing compounds, and other bond inhibiting contaminants.
Pre-mix each component thoroughly. Place 2 part by volume of component A and 1 part by volume of component B into a clean pail. Mix thoroughly for 3 minutes with low speed drill using agitator’s mixer until uniformly blended.
Applications Methods
After shot blasting to expose all bug holes, apply the first primer to bond substrates and putty. Work into the bug holes and scrape off excess material, applying the repaired putty to filling bug holes, pinholes and defects. Surface should be strike off level, and then apply the second primer. Allow Qtech-112 to become dry to the touch prior coating with Qtech serial polyurea system.
Application Conditions
           Air and surface: -20°C ~100 °C
       No standing water on working surface
       Materials must be preheated to 15°C prior to use.
1.   Store drums and pails in a cold, dry and ventilated location between 15°C and 40°C.
2.   Six months in sealed unopened containers.
3.   Keep away from fire and heat source.
4.   Keep away from rain and sun.
Read and understand the MSDS provided with all shipments. Always use products with adequate ventilation and use required PPE. For confined space use fresh air supply. For open air, use half face, twin cartridge respirators approved. Always protect eyes and skin. Strictly adhere to industry safety standards.
Dispose of in accordance with local and international disposal regulation.
1.  Reading and understand the production information.
2.  This product is intended for industrial use by properly trained professional applicators only.
3.  Adding a nitrogen blanket is strongly recommended for use on the “A” component for storage after opening.
4.  The quality and fitness of the product is depending upon the proper mixture and application of the component by the applicator.
5.  This specification is an accumulation of long term testing and experience. Published technical data and instructions are subject to change without notice.
