2. Excellent weather resistance, aging resistance, and UV resistance
3. Excellent adhesion, filling sealing, flame retardant and fire retardant properties
4. It is used for bonding and sealing aluminum plates, steel plates, leather, plastics, fibers, etc
Product Description:
QLD980 polyurethane rigid foam
1:1 ratio, rapid foaming and curing, forming a hard foam insulation layer. It is used for foaming and sealing the thermal insulation layer of refrigerated trucks, RVs, refrigerators, pipe holes, etc.
QLD985 polyurethane adhesive
It has excellent flexibility and adhesion. It is used in the bonding of leather and substrates for trains, buses, vehicles, machinery and equipment, etc.; It can also be used for potting and bonding of paper or fiber filter elements with steel plates or plastics, and can also be used to produce filter end caps by pouring.

Note: Measured at 25°C, 55% relative humidity, curing for 7 days. Temperature resistance range of cured colloid: -60~120°C
Usage:
1. The surface to be bonded should be cleaned, remove oil and dust, and dry thoroughly, and there should be no foreign matter such as oil and water on the surface, otherwise it will affect the adhesive strength.
2. Stir material A in the barrel before batching, mix material A and material B according to the ratio, stir fully and scrape the wall, and mix evenly.
3. When using rigid foam glue, calculate the amount of glue, the amount = cavity volume / foaming multiple, and increase the amount appropriately to obtain overfill seal; When the floor leather is bonded, pour the mixed glue on the board, and scrape the glue evenly with a scraper, so that the glue is evenly applied without leakage and scraping, and the optimal glue amount is 200~300g/m, cover the leather above, pay attention to the air between the two adhesive surfaces, and achieve smoothness without waves; When the filter element is filled, inject an appropriate amount of glue into the end cover and place it for a while, so that the glue surface is evenly coated on all parts, insert the filter paper (or add the center tube) into the end cover, check the surface of the two glue joints to ensure that they are completely in contact, and then stand under a little pressure at the top end, and after about 1 hour of curing, flip and glue with the other end cover.
4. After 24 hours of complete drying, it can be trimmed and packaged by traditional methods.
Precautions:
1. Avoid construction in a humid environment below 15°C and humidity greater than 90%.
2. The rubber material is stored for a long time, and there will be delamination, so it can be stirred evenly before use
3. Store in a dry environment at 10~27°C, with a shelf life of 6 months
