Polyurethane Resin, as a polymer material with high strength, tear resistance, wear resistance and other properties, is widely used in daily life, industrial and agricultural production, medicine and other fields.

Polyurethane elastomers are used in rollers, conveyor belts, hoses, auto parts, shoe soles, synthetic leather, wires and cables, and medical artificial organs; soft foams are used in vehicles and homes

, sound absorption, packaging, insulation and low foaming synthetic wood, coatings for high-end vehicles, furniture, wood and metal protection, pools Anti-leakage materials for dams and buildings, and fabric coatings, etc. The adhesive has good adhesion to metal, glass, ceramics, leather, fibers, etc. In addition, polyurethane can also be made into emulsions, magnetic materials, etc.

Soft glue

Polyurethane resin soft glue is a two-component, room-temperature curing glue developed from polymer materials, with low viscosity, low odor, softness and transparency. Resistant to wear, yellowing, UV aging, never hardening, suitable for outdoor use. Suitable for manual glue dispensing and machine glue dispensing.

The main features of polyurethane resin soft glue are:

1. Anti-radiation, it will not yellow or harden after exposure to sunlight or ultraviolet rays, and is suitable for outdoor products.

2. Resistant to UV aging.

3. It will not harden, break, shrink or warp after long-term use, and does not affect the viscosity. Resistant to outdoor sunlight.

4. The mixed glue has low viscosity and good leveling properties.

Polyurethane resin soft glue is mainly suitable for: outdoor signs, trademarks, jewelry, mirrors, handicrafts and other product surfaces. It can also be used for potting products. It has excellent softness and adhesion. Such as car and motorcycle signs, etc.

Operating technology:

1. Work under ventilated and breathable conditions.

2. Use clean tools that are free of water, oil, and chemical solvents.

3. Accurately weigh A/B. (More component A will cause bubbling at the bottom, and more component B will cause the surface to become sticky).

4. Stir carefully in the same direction to avoid producing a large number of bubbles. If there are filaments in the glue, you need to stir patiently until it is completely transparent.

5. Defoaming: Use a vacuum degassing machine to defoam, or use flame or hot air to sweep the glued product.

Notes:

1. Manual glue dispensing has high environmental humidity requirements. Only when the relative humidity is within 60% will no blistering occur. It is best to install a dehumidifier.

2. Do not use moisture-containing tools such as wood. It is best to use metal or plastic tools.

3. The substrate must be dry, and inks containing glycerin cannot be used.

4. Contact of this product (especially B glue) with skin may cause allergies. Please prevent skin contact. If in contact, please wash with plenty of water and soap.

5. Mixing large quantities of glue will produce rapid solidification and high temperatures.

6. Industrial materials, keep away from children and prevent consumption.
