Coatings are made up of resin, additives, and a liquefying agent that’s either “water-based” or “solvent-based”. Water-based coatings and solvent-based coatings have distinct purposes that depend on your needs. One coating may work better under mild weather conditions.

Water-based coatings and solvent-based coatings have distinct purposes that depend on your needs. One coating may work better under mild weather conditions. Another coating may fit a job that involves a lot of heavy handling.
Water or Solvent Based?
Water-based coatings are present on items that may be in close proximity to people. Household paints, for instance, are most likely water based. Projects where people are working in confined spaces can involve items that are covered in a water-based coating. This type of coating doesn’t necessarily mean zero solvents.
Solvent-based coatings are intended to withstand certain climates, and more wear and tear than its water-based counterparts. If you’re working in a climate that is very humid, choosing materials with a water-based coating may actually prevent the water from evaporating. , they point out solvent based sealers create a continuous film which can prevent moisture from seeping in.
This is where Helix’s PTFE coating comes in.
The Helix Linear PTFE coating is hard and solvent based. It doesn’t flake or chip. The PTFE coating creates a permanent and low friction surface from lead screw to nut. Our PTFE coating is resistant to oils, chemicals, cutting fluids, coolants, and is less susceptible to peeling off in harsh environments or installations.
Some soft PTFE coatings will transfer particles from screw to nut. The Helix PTFE coating is designed to stay on the lead screw, which in turn provides longer life since nut wear is significantly reduced. Our testing consistently shows that nut life increases by 8 to 10 times, without additional grease or lubricants having to be added. With our coating, the friction coefficient is cut from .15 to .08 on a stainless steel screw. This increases efficiency by 5% over an uncoated screw.
