R & A HM FC

R & A HM FC is one part high modulus and high viscosity polyurethane sealant. It is quick setting and air moisture curing sealant. It provides a permanent ,elastic and high strength bonding. The sealant has a very good resistance to ageing and harsh weather.

AREA FOR APPLICATION

HM FC is highly recommended for the bonding and jointing sealing of the windscreen and side windows in the automotive and transportation tool manufacture, also could be used in coach glass joint smooth with excellent aspects. It provides an excellent adhesion on materials like glass, ceramic, painted or naked metal(Aluminum, steel ,Etc.),and therefore can also be used as bonding sealant in different kind of application.

INSTRUCTIONS

Substrate preparation. The substrates to be assembled must be dry, clean, free of oil and other contaminants that could adversely affect the bonding performance. The substrates to be assembled are first treated with the cleaner, When the cleaner is dry, apply the primer .When using cleaner or primer, keep away from all sources of ignition and carefully follow the safety and the handling instructions given by the manufacturer or supplier.

Installation

When the primer is completely dry, HM FC to be applied with a hand or pneumatic gun to one substrates,and pressed it on the second substrate before it skinned. Do not apply it at temperatures under 5℃. In cold weather, store the sausages at 20℃ before use. Do not apply on silicones or in presence of polymerized silicones or hybrid sealants (MS or SPUR).

Cleaning

Tools should be cleaned with MEK or acetone before curing. After curing, mechanical cleaning is necessary.

STORAGE AND SHELF LIFE

12 months in the original cartridges and sausages, and 6 monthes in the drum. Hermetically store the products between 5 and 25℃

PACKAGING
