MF205 polyurethane sealant
product Description:
MF205 polyurethane sealant is a high-quality, multi-purpose, anti-sagging, one-component polyurethane sealant, which reacts with moisture in the air to cure to form a permanent elastomer. MF205 is manufactured in strict accordance with the ISO900114001 quality assurance system and related protection regulations.
product manual:
MF205 polyurethane sealant is a high-quality, multi-purpose, anti-sagging, one-component polyurethane sealant, which reacts with moisture in the air to cure to form a permanent elastomer. MF205 is manufactured in strict accordance with ISO9001 1 14001 quality assurance system and related protection regulations.
Product superiority:
Single component
Anti-aging
Low odor
No corrosion
Excellent construction characteristics
Good adhesion to many substrates
Anti-yellowing
Scope of application:
MF205 has good adhesion to a variety of substrates. It is suitable for permanent elastic seals that require higher bonding strength. Suitable substrates include wood, metal, metal primers and topcoats, ceramic materials and plastics. This product is only for users with professional skills. In order to ensure the bonding effect and the compatibility of the product and the material, tests should be done in advance under the actual substrate and environment.
Curing method:
MF205 cures by reacting with moisture in the air. Generally, the lower the temperature, the lower the moisture contained in the air, so the reaction process will also slow down.
Chemical resistance:
MF205 is acid, alkaline, neutral and chlor-alkali-resistant detergent; short-term resistant to fuel, mineral oil, animal fat and crude oil; not resistant to organic acids, concentrated inorganic acid and alkali solutions or solvents.
The above description is only a general guide. For special applications, we will provide suggestions on request.
Construction method:
Requirements for the workshop The work site and the surface of the workpiece must be clean, dust, moisture and other air pollution. The work area must be isolated from pollution caused by nearby production. Grinding, welding, and any work activities that contain silicone resin in solvents or materials are prohibited in the 30m area around the work site.
Excellent adhesion to a wide range of substrates including coated, enamelled and reflective glasses, anodised and polyester paint coated aluminium and stainless steel.
Excellent temperature stability: - 60°C t 1ao0c.
High level of mechanical properties.
High elasticity and high modulus.
Resistant to ozone.
