The Pur Moulding System, PMS-4, is succesfully used for inset light fixing and cable chase in both ashpalt and concrete, primarily in airfields. It is a quick hardening system and after only a few minutes of curing, the road or runway can be trafficked again.
PMS-4 is a two-component polyurethane system of solid type, made of products known to be high in thermostability and with great impact resistance.
The thermostability is very high, > 100°C. This is an important factor to keep the bases in fixed position when the temperature in the ground is high.
The unique quality and moulding method of PMS-4 opened new markets, where it so far had been impossible to use polyurethane material. The PMS-4 moulding method keeps the bases in a fixed position in all climates, without sinking, twisting or changing position.
