APPLICATION METHODS
◆ PREPARING
Before mixing, Part A and Part B should be agitated well to obtain uniform elastomer. Care should be taken to minimize air entrapment.
◆ MIXING
Thoroughly mix Part A and Part B in a ratio of 1:1 by weight. The liquid mixture should have a uniform appearance. The presence of light-colored streaks of marbling indicates inadequate mixing and will result in incomplete cure. It can be automated mixing or manual mixing.
◆ DEFOAMING
When practical, pouring/dispensing should be done under vacuum, particularly if the component being potted or encapsulated has many small voids.
◆ CURING
Cure reaction begins with the mixing process. Initially, the mixture of Part A and Part B can be poured/dispensed directly into the container in which it is to be cured. Cure is evidenced by a gradual increase in viscosity, followed by gelation and conversion to a solid elastomer. Pot life is sensitive to environmental temperature.
COMPATIBILITY
Certain materials, chemicals, curing agents and plasticizers can inhibit the cure of SLF385 silicone encapsulant. Most notable of these include:
◆ Organotin and other organometallic compounds
◆ Silicone rubber containing organotin catalyst
◆ Sulfur, polysulfides, polysulfones or other sulfurcontaining materials
◆ Amines, urethanes or amine-containing materials
◆ Unsaturated hydrocarbon plasticizers
◆ Some solder flux residues
If a substrate or material is questionable with respect to potentially causinginhibition of cure, it is recommendedthat a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured gel indicates incompatibility and inhibition of cure.
REPAIRABILITY
SLF385 silicone encapsulant can be selectively removed with relative ease, any repairs or changes accomplished, and the repaired area repotted in place with additional product.
PACKING INFORMATION
SLF385 silicone 1:1 mix ratio encapsulants are available in 25kg/25kg plastic tub by set.
USABLE LIFE AND STORAGE
