What are the precautions for the use of textile compound glue?
Textile compound adhesive is a kind of adhesive with urethane or isocyanate groups in the molecular chain. Textile compound glue can be divided into polyisocyanate and polyurethane. The molecular chain of polyisocyanate contains isocyanate and urethane, so the textile composite rubber has high activity and high performance.

The molecular chain of polyisocyanate contains isocyanate and urethane, so the textile composite rubber has high activity and high performance. The following is the use of textile compound glue:
1. Surface treatment: Use sandpaper to polish the adhesive surface to remove rust, and then clean and dry for standby.
2. Glue JL-6810 heat-resistant single-component textile composite glue can be evenly coated on the surface of the adherend by rolling, coating, brushing, spraying and then scraping.
3. Pressurize 0.1Mpa on the surface of the coated article, squeeze out the excess glue and wipe it clean.
4. Curing. Early winter curing time is about 78H, about 3H in summer. If a catalyst is added, the curing time can be accelerated by 2 days.
5. Use the intensity of long-term use of about 100C, short-term use of 120C, instant use of 150C.
So what are the precautions for the use of textile compound glue?
Due to different product requirements, the amount of glue applied to each product is also different. On the other hand, the choice of competition is determined according to the type of product not used, and the appropriate selection of the amount of glue can have a very good product bonding strength. If the amount of glue applied is too small, the peel strength of the product will be insufficient. If the amount of glue applied to the product is too large, it is easy to cause the glue to dry out during the curing process.
In this way, in the subsequent production process, it is easy to cause some unnecessary troubles, and once the glue is dry, the subsequent production is very difficult. So the amount of textile compound glue must be carefully selected. This is a good choice when used, which is important. Otherwise, after the product is provided to customers, quality accidents are prone to occur, and the product quality is difficult to guarantee.
Textile compound glue is crystal clear, anti-bending, anti-aging, anti-yellowing, strong adhesion, fast curing speed. Scope of application: PVC signs, automotive panels, motorcycle decals, stickers signs, etc. Requires high product drop coating mixing ratio: A1: B1 curing time: 60 room temperature 12 hours 1.5 hours. Textile compound glue is widely used as trademark material because of its plump surface, abrasion resistance, impact resistance, yellowing resistance, UV aging resistance, non-hardening and long-term stability. Two-component polyurethane resin, clear and transparent, anti-ultraviolet, suitable for outdoor use. Can be used artificial or machine drop glue.
