Applications & Uses

Product Applications

• Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting.
• During prolonged stops, the temperature of the adhesive must be low- ered.

Product Benefits

• Open time vs setting time behavior: With conventional EVA and APAO hot melt adhesives, the open time and the setting time are usually related. Rakoll 5437 Plus is a polyolefin hot melt adhesive that combines a very short setting time with a very long open time.

• Offers the same performance with up to 15% less consumption: Compared to standard products it has a lower density which has a direct impact on the coating weight.

Coating weight of rakoll 5437 plus compared with standard hot melts:

• Excellent thermal stability: no skin formation, compared to EVA and APAO, allowing a cleaner production process and a better working environment

• Better melting properties than APAO-based hot melts, with smoother spreading and lower consumption of energy. Better surface quality.
