JOINFLEX 202 High Performance PU Foam

PRODUCT DESCRIPTION

JOINFLEX 202 High Performance PU Foam is a one-component, self-inflated, high extrusion capacity, multi-purpose Polyurethane foam, which will expand and cure by moisture in the air.

JOINFLEX 202 High Performance PU Foam has good adhesion for most materials and excellent filling properties, installed capacity, stability.

Cured product provides excellent thermal and acoustical insulation. It is mould proof, resistant to heat and cold (-60ºC to +100ºC), and moisture-resistant.

FEATURES

Can be cut and painted

High adhesion to most building materials

Excellent gap filling properties

Good insulation characteristics

Filling joints cracks and gaps in insulating panels and sheets

Excellently suitable as foam for sealing and connecting precast concrete well shaft rings.

Quick-curing foam with excellent adherence and insulating capacity

It contains CFC-free propellants which are harmless to the ozone layer.

APPLICATION LIMITS

JOINFLEX 202 High Performance PU Foam is not suitable for adapting to structural fitting and following situations:

1. To all surfaces that bleed oil, plasticizers or solvents such as wood immersed in oil, oil crack filler, and some uncured or sulfurized fat and to surface where is wet;

2. To the substrate that the surface temperature exceeds +50°C or apply at temperatures below 5°C;

3. Use in the manufacturer of IG units;

4. To the painted surfaces, may cause seal failure as the paint cracking or stripping;

5. To the surfaces that with direct touch of food.

6. Do not use for structural glazing.

7. Not recommended for continuous water immersion applications.

8. Not recommended for use in below ground joints or trafficable

9. Joints where abrasion and physical abuse are encountered.

10. Not recommended for some plastics such as plastic, paper, and fabric.

HOW TO USE

APPLICATION TEMPERATURE:   +5°C to +35°C

Cleanse with a cleaning agent, to keep the substrate surfaces completely clean(JOIN LEADER also provide the cleaning agent for your convenience).

Use the sealant after cleaning agent dries, around 1~2mins later. You can use two different cloth, one for cleaning agent, and the other for sealant. (Notice that the two can’t be mixed use together, and the second cloth will be better purified cotton and no picking.)

Fill vertical gaps from the bottom up (pay attention to foam expansion).

Turn off the flow adjustment screw clockwise direction when finishing.

Before curing, foam can be moved and cleaned with PU cleaner either with the gun or with adapter.

Cleaning of the screw adapter with cleaner is recommended.

Do not expose to UV rays. Painting or coating is recommended.

 

SHELF LIFE

12 months in unopened packaging in a cool and dry storage place at temperatures between +5°C and 27°C.

Always keep the can with the valve pointed upwards.
