- Conductor entry holes
- Surface Preparation
All surfaces should be clean and dry, and free of dust, dirt, and grease. It is recommended that bonding surfaces be wiped with an oil-free solvent. Allow surface to dry thoroughly before applying sealant. CSL588 has excellent unprimed adhesion to most substrates.
- Application
CSL588 is ready-to-use and requires no mixing or additives. Curing begins as soon as the sealant is exposed to air. At conditions of 25°C (77°F) and 50% relative humidity, a bead of sealant, 3mm, will skin over in 5 - 10 minutes and fully cure in 24 hours, attaining full physical properties in 7 days. Higher humidity accelerates cure. Cure time will also vary with the degree of confinement. Tooling, if necessary, should be done before skin-over takes place.
In confined cure conditions, CSL588 neutral cure sealant may discolor brass, copper, or other sensitive metals, and/or stress craze polycarbonate.
CSL588 should not be applied below grade, to surfaces under continuous water immersion, to substrates that bleed oils, plasticizers or solvents (e.g. impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes), to surfaces in direct contact with food, and to surfaces that will be painted over.

Safety & Health
- Safety Precautions
CSL588 uses a neutral cure system, so no acetic acid or objectionable by-products are evolved during the cure. Adequate ventilation should be provided with extensive use of this sealant.
On direct contact, the uncured sealant may irritate the eyes. Flush well with water and call a physician. Avoid prolonged contact with skin. See Safety Data Sheet available on this product.
All work involving the application and use of this product should be performed in compliance with all relevant national, Health, Safety & Environmental standards & regulations.
