Tremco Tremflex 50 Joint Sealant

TREMflex 50 bonds tenaciously without the assistance of a primer, however some substrates will require primer to develop adhesion.

Tremco Tremflex 50 Description

TREMflex 50 is a low modulus joint sealant, especially formulated to ensure bubble free cure even at very high temperatures and humidity climatic conditions. It cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor. The sealant guns and tools consistently well at even the most extreme temperatures.

Usage/Purpose

TREMflex 50 can be used for sealing joints in:

• Under waterproofing membranes
• Cast In Place concrete
• Precast panels
• Brick & block work
• Metal

Features & Benefits

• No bubbling/swelling upon curing in difficult climatic conditions.
• Excellent adhesion on a wide variety of substrates without priming necessary.
• Excellent extrusion, tooling & storage stability over wide range of climatic conditions.
• Good chemical resistance.
• Low modulus, joint movement accommodation +/- 50%.
• Microorganism & fungus resistant.
• Excellent heat resistance, suitable for application where exposure to temperatures >60oC take place.
• Resistance to cold: The sealant remains elastic even down to -40oC.

Do not:

• Use on glass, natural rubbers such as EPDM, PVC or TPO.
• Use on bitumen will result in discolouration.

Allow to fully cure prior to installation of nearby silicones.
