JY900 Multi Pupose PU Foam Spray 750ml

JY900 Multi Purpose is a single-component, moisture-curing polyurethane foam.It is designed for easy dispensing through both the straw adapter and applicator gun. Its cellular matrix demonstrates remarkable bonding effectiveness across diverse substrates while providing accelerated solidification and exceptional thermal resistance., With its good adhesion on all surfaces as well as fast curing and insulation properties, it is recommended for use in construction projects for window and door installation, gap filling, joint of cavities in roof constructions and thermal isolation in cooling systems.

Product Operate Guide

1.Before The Construction, Should Remove The Construction Surface Oil And Floating Dust, And

A Small Amount Of Water Sprayed On The Construction Surface.

2.In The Temperature Range From 0 ° C To 40 ° C, It Is Suggested To Preheat The Tank In The

Environment Of 30 ° C In Order To Ensure The Effect Of The Construction In The Cold Season.

3.Before Use, Shake The Polyurethane Foam Caulking Agent Tank For At Least 60 Seconds To

Ensure That The Material In The Tank Is Even.

4.If The Gun-Type One-Component Polyurethane Foam Sealant Is Used, The Feed Tank Is Inverted And Connected With The Spray Gun Thread, The Flow Valve Is Rotated To Open, And The Flow Rate Is Adjusted Before The Spray.

FAQ

How should expansion behavior be controlled during application?

The product expands 2-3 times after dispensing - apply in sequential layers for deep cavities and lightly mist with water to optimize curing.
What surface preparation ensures optimal adhesion?

Substrates must be clean and dust-free; lightly dampening surfaces with water significantly enhances both adhesion and curing speed.
How is excess foam effectively removed after curing?

Fully cured material can be cleanly trimmed with a serrated knife or specialized foam cutter for a smooth finish.
What protective measures are required during use?

Wear disposable gloves and protective glasses, as uncured material is difficult to remove from skin and clothing.
How does temperature affect expansion and curing performance?

Optimal application temperature ranges from 5°C to 30°C; colder conditions slow curing while excessive heat accelerates expansion.
