◣ Advantages of the SDP1237 Ultra-Low-Temperature (–20°C) Construction Spray Product

● The SDP1237 spray‑applied foam can be applied in ambient temperatures ranging from –20°C to 40°C, and exhibits excellent adhesion even when sprayed at low temperatures.

● SDP1237 spray‑on foam is suitable for temperatures ranging from –60 to 80°C, can withstand a wide ambient temperature range, and has a broad spectrum of applications.

● LBA blowing agents feature an ODP of 0, a low GWP, no ozone depletion potential, and minimal impact on the greenhouse effect.

● Low thermal conductivity and seamless continuous spraying ensure excellent thermal insulation. It exhibits low water absorption and ideal impermeability.

● The single-layer coating can reach a thickness of 50–80 mm, exhibiting high compressive and tensile strength, excellent dimensional stability, and a long service life.

◣ Scope of Application

It is widely used in winter construction for wall insulation, as well as in the renovation and replenishment of cold-storage insulation projects during operation.
