nC® ProTect 4400 Hull Sealant in short

nC® Protect 4400 Hull Sealant is a transparent coating developed to protect materials from abrasion, absorption and polluting. It can be applied on polyester, UHMWPE (Dyneema, Spectra), (U)HDPE, PMMA, kevlar, metals, aluminium and stainless steel. nC®  Protect 4400 Hull Sealant is approved for foodcontact according to FDA specifications.

nC® Protect 4400 Hull Sealant bonds chemically into materials and their surfaces. It forms a matrix inside the material. The exterior becomes a very flexible ultra-thin, glass-like finish and lasting soiling protection. Consequently, this finish is very suitable to protect against negative chemical and environmental influences. It is user ready and can be applied by brush, roller, cloth and airgun (HVLP).

This product is intended for professional use by persons familiar with this product data sheet, the Material Safety Data Sheet (MSDS) that accompanies product shipments, and applicable health, safety, and environmental practices and regulations.

  • Use tight fitting safety glasses.
  • Ensure adequate ventilation, use suitable respiratory equipment, use of combination filter A2 B2 E2 K2 Hg/P3, to standard DIN EN 371/372 is recommended.
  • Protect hands and skin from exposure using gloves and appropriate clothing. Gloves should be solvent-resistant (butyl-rubber) and >0,5mm of thickness and satisfy standard EN 374 from directive EU 89/686/EEC. Protective clothing category 3, type 3, liquid tight, anti-static.
  • Do not eat, drink or smoke during application.
  • Substrate must be free from grease, dirt, dust and water or moist.
  • Substrate temperature must be between 5° C and 50° C.
  • Do not apply when ambient humidity exceeds 80%.
  • Avoid direct sunlight during application.
  • Do not let nC® Protect 4400 Hull Sealant make contact with water during application or during cure time (first 12 hours). When in contact with water during application, nC® Protect 4400 Hull Sealant will react with H2O prematurely instead of reacting with the surface, thus influencing the long-term bonding and tear-off rate of the coating.
  • Product is ready to use. DO NOT USE ANY THINNER!
  • Film thicknesses can be varied from between 5 – 20 µm, depending on application conditions.
  • Application rate varies between 10ml to 15ml per m²
  • nC® Protect 4400 Hull Sealant is very thin and fluid, take care not to use too much product!
  • In case of HVLP application use 2 – 3 bar pressure and 0,8mm – 1,3mm nozzle.
  • Keep uncured product from flame, all ignition sources, and moisture.
  • nC® Protect 4400 Hull Sealant must be applied in one go. Because of the repelling characteristics of the coating, stains, open spots or other mistakes can be repaired within 10 minutes after first application. After 10 minutes, the coating starts to repel any layer that will be applied, including paint, solvent or other fluids.
  • Dry to touch in ambient temperatures above 10° C : 2 to 3 hours
  • Curing times, after which coating can be put into full operation:
  • Ambient temperatures between 10° C and 20° C: 24 hours;
  • Heated to 60° C for 15 minutes: 3 hours;
  • Heated to 80° C for 15 minutes: 2 hours;
  • Heated to 180° C for 15 minutes: 1 hour;
  • Full strength will be reached after 3 to 5 days.
  • Clean unintended coated or dripped surfaces immediately with (butyl)acetone or mineral spirits. Solvent cleaning can be followed by a wash with soapy water. Cured material cannot be removed with solvent. Proper clean-up of equipment is essential.

The product is dry to touch within 2 up to 3 hours. As nanotechnology is about bonding into surfaces and matrices of nanoparticles need to be built up after application, the coating reaches full insulating ability AFTER a cure time of approximately 3 to 5 days, which is dependent upon environmental variables, humidity, and thickness of coat used. Test of maximum performance should be performed after full cure. Benefits will typically begin to be seen approximately 24 hours after application, and will continue to improve as the cure time completes. Cure time won’t interfere with normal operations, you can start using the treated materials after 24 hours and continue to use your equipment as usual while the product cures.
