Disperse 5 to 10 kg of LONGEE 500CHL per 1000 Liter of exterior paint to obtain effective mildew control in the paint film after it is applied. Use the high rate in areas favorable to mildew and mold growth, such as where painted surfaces frequently are warm and moist. LONGEE 500CHL, when added to stains designed for exterior wood, also protects the wood from surface molds and mildew stains caused by fungi. Use 5 to 10 kg of LONGEE 500CHL per 1000 liters of interior latex paint.
LONGEE 500CHL is compatible with zinc oxide
in latex paints.
LONGEE 500CHL can be used with either unmodified or alkyd modified acrylic, vinyl acrylic, or polyvinyl acetate latexes.
Longee 500CHL can be added into the paint formula during the pigment grind operation, during or after letdown, or post-added to a finished paint product after manufacture.
Note: If Longee 500CHL is used to produce post-manufacturing paint additive products, such products must be distributed to and used by only professional personnel engaged in the mixing or blending of paints. Such post-manufacturing paint additive products may not be sold directly to homeowners or non-professional painters.
If an in-can preservative is used in combination with LONGEE 500CHL, its compatibility with LONGEE 500CHL should be examined first.
DO NOT use in paints designed for applications on food-contact surfaces, or on the interior of buildings engaged in food processing or food handling. DO NOT use in paints designed to be handled by children.

LONGEE 500CHL may be incorporated into adhesives to protect the applied adhesive films from mold growth and decomposition. Fully disperse 6 to 12 kg of LONGEE 500CHL per 1000kg of adhesive while it is being manufactured. Use the high rate in areas favorable to mildew and mold growth, such as where surfaces frequently are warm and moist.
DO NOT use in adhesives designed for applications on food-contact surfaces, or on the interior of buildings engaged in food processing or food handling.

To provide mildew and mold control on caulking or sealing deposits after application, fully disperse 5 to 8 kg of LONGEE 500CHL per 1000 kg of caulk or sealant products while they are being manufactured. The high rate is recommended for exterior caulks.
DO NOT use in caulks or sealants designed for applications on food-contact surfaces, or on the interior of buildings engaged in food processing or food handling.

To prevent sapstain and surface mold growth on freshly sawn wood, mix LONGEE 500CHL into water-based dip treatment suspensions at the rate of 5 to 10 kg per 1000 kg of water. Use the high rate if the wood to be treated is expected to remain in undried condition for a prolonged period. Dip freshly-sawn wood products into the treatment suspension for sufficient time to permit thorough coating of the wood surfaces. Maintain thorough agitation of the treatment suspension
while wood is being treated. Store treated wood in an area that is not subject to runoff into surface waters. Do not dispose of spent treatment suspensions in any manner that may contaminate soil or water.

To provide decay protection for composite wood products, such as flakeboard or particle board that is to be used for building siding, sheathing, construction timbers, decking or planking, incorporate LONGEE 500CHL into the wood composite material while it is being manufactured. Use 5 to 10 kg of LONGEE 500CHL per 1 cubic meter volume of final wood composite. The high loading rate should be used in composite wood products that are intended to be installed in contact with soil or concrete, or where the wood is intended to be exposed to conditions with continuously high levels of moisture. Thoroughly incorporate LONGEE 500CHL into the composite material as it is being ground, mixed or blended with adhesives or binding materials prior to final formation of the wood composite matrix.
