Novagard® RTV 800 Series

Novagard® UV Curable Sealants – 800 Series

Novagard® Silicones UV cured inks and coatings maintain all of the enhanced performance characteristics of conventional silicone based materials with processing speeds unmatched by other technologies. Based on patented, ultraviolet-energy cure chemistry exclusively available from Novagard® Silicones, the 800 Series products possess a speed and depth of cure far exceeding most other UV cure systems. This unique chemistry allows deep sections to cure almost instantly. If desired, a moisture curable component provides for shadow curing in those areas unexposed to the ultraviolet light source.

Silicone Properties with UV Speed are :

• Adhesion to most common substrates including plastics and metals
• Excellent thermal stability and weather resistance
• Transparent/translucent systems as well as highly pigmented formulations
• Dielectric properties expected from a silicone
• Unique, all new patented UV-cure chemistry (U.S. Pat. No. 7,105,584)
• Solvent Free / 100% solids – no VOCs to handle or report
• Extremely flexible, high elasticity with a soft touch and no tackiness
• Service Temperature of -54°C to 260°C

Description: The Novagard UV/Dual cure sealants are available in flowables, pastes and gels. These products will cure within three seconds when exposed to a UV light source. They are ideal for increasing through-put and eliminating the need to rack parts. Our paste products can be foamed up to 1/4” thick to reduce material costs.

Special Characteristics: Production line speed cure rate (~3 seconds), depth of cure up to 5/8” depending on product. Requires minimal UV energy source. *Approved under UL746E for indoor and outdoor usage on printed circuit boards as a conformal coating:

Generalities

Material Compatibility

Generally, silicone materials have the following impact on material properties:
Silicone Rubber – Tends to swell, soften and decrease in tensile strength.
Fluoro Rubber – No effect.
Organic Rubber – Slight shrinkage, hardening and loss of physical properties.
Plastic – No effect on polycarbonate, phenolic, polystyrene nylon, methacrylics or PTFE. Slight
swelling or shrinkage may occur in polyacetal, polyethylene, polypropylene or PVC.

Methods of Application

Silicone greases and compounds may be wiped on, brushed on, dispensed from a grease gun or applied by automated equipment. In addition, when dispersed in a non-polar solvent they may be applied by brushing, spraying or dip coating. Caution is required in the selection of solvents.

Handling and Safety

Material Safety Data sheets are available upon request from Novagard Solutions.

Cleanup of silicone greases and compounds can be accomplished using non-polar solvents such as mineral spirits. They are soluble in stoddard solvent, toluene and xylene. Caution should be observed whenever handling solvents.

Silicone greases are not suitable for use in contact with high concentrations of oxygen or highly oxidative materials. Contact with high pressure oxygen, ozone, peroxides or fuming nitric acid can result in fire or explosion. Silicone materials are damaged by exposure to strong mineral acids (e.g. sulfuric, hydrochloric, nitric), strong alkaline (e.g. sodium or potassium hydroxides), nitrates or peroxides.
