Metal coatings, leather coatings, garage floor coatings, swimming pool coatings, extreme trailer coatings and concrete densifier and sealer coatings, these are the different types of coatings. The power which they materials have is helpful in resisting household chemicals, mechanical shocks and scratches and this is one of the paramount reasons to use epoxy floor coatings. People often use waterborne polyurethane for their garage floors, where cars, chemical treatments and heavy pieces of furniture and equipment are kept.
Water bond epoxy floor coating cannot hide cracks, however they are user-friendly. Water based epoxy floor coatings are generally used for residential purposes, whereas industrial and rough coat epoxies are suited for commercial and industrial uses. Water based epoxy floor coating is perfect for garages and is both a primer and a topcoat.
Epoxy, polyurethane, acrylic sealer or stain or latex c are different types of garage floor coatings. Epoxy forms a durable surface and bonds well the concrete under it. Chemical spills can be resist by polyurethane can resist. Acrylic sealers or stains are like latex paints are inexpensive and make it look great. By using these waterborne coatings we can escape the garage floor from a lot of wear and tear and make it look wonderful.

Reactive Diluents – Ideal for Polyurethane Coatings
A large number of formulators come across a question about developing a high-solids polyurethane system with low viscosity for feasible application, as well as incredible performance after curing process since voc component in paints and coatings became the prime focus of regulations.
Scientists have found an answer to this problem by making the use of low molecular weights polyols to deliver a lower viscosity formulation that need less solvent. Unfortunately, these reductions in molecular weight sometimes lead to systems that cure too quickly and unable to perform well in the field. These polyols pose a threat of high intrin
sic viscosities without reductions in molecular weight which makes it very intrinsic to eliminate solvent from the formulation.
On the other hand, Reactive diluents are low viscosity co reactants that are developed purposefully to reduce VOCs with the help of a reaction with the polymer matrix. They are very much similar to solvents as they reduce polymer viscosity, but they do so without increasing VOCs. Reactive diluents typically take the form of blocked or delayed sources of active hydrogen. For example – Aldimines and ketimines are block-amino compounds. Oxazolidines are also a part of blocked amino alcohols.
