pu foam detail


SIWAY PU FOAM is a one-component, economical type and good performance Polyurethane foam. It is fitted with a plastic adapter head for use with a foam application gun or a straw. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation. It is environmental friendly as it does not contains any CFC materials.

1.Bset Tensile Strength

80% of foaming agent immediately after blowing foam, foam behind the range is very small, high expansion ratio, significant savings in renovation costs

2.The color is white

3.Foaming evenly

Color white beautiful

Foaming agent section smooth

How to use

Step 1

PU foam is shaken up and down for 1 minute before use

Step 2

Clean and moisturize the construction surface before application

Step 3

Connect the tank upside down to the gun and turn the valve open to adjust the flow

Step 4

Spray from the bottom up, the injection volume is 1/2 the required fill volume

Step 5

Ten minutes after the foam began to cure, 1 hour after the next step

Step 6

Cured foam can be removed with a sharp knife excess, and then in the surface with cement mortar, paint or silicone sealant for processing

Application Instrucions

3.The flow rate of the foam can be adjusted by the control panel.
4.Shake the container for 1 minute before using, connect material container with spray gun or spray pipe, the filler content is 1/2 of the gap.
5.Use dedicated cleaning agent to clean the gun Surface drying time is about 5 minutes, and it can be cut after 30 minutes, after 1 hour the foam will be cured and achieve stable in 3-5 hours.
6.This product is not UV-proof, so it is suggested to be cut and coated after the foam curing (such as cement mortar, coatings, etc.)
7.Construction when temperature is lower than -10 ℃, to ensure the material can be exhausted and increase the foam expansion, it should be heated by 40 ℃ to 50 ℃ warm water

Storeage and Shelf Life

12 months in unopened packing store in temperature between +5℃ to +25℃, Keep in cool, shade and well ventilated area. Always keep the can with the valve pointed upwards.

Safety Recommendation

1. Store the product in a dry, cool and atmospheric place with temperature under 45℃.
2. The after-use container is forbidden to be burnt or punctured
