Advantages: good corrosion protection; excellent gloss/UV resistance; fast drying and recoating time; good hardness development; good chemical resistance (ISO 12944); high flash point; good adhesion to coatings and metals; low dirt pick up (topcoats); high degree of flexibility; non-chalking and non-yellowing; very good water-resistance; competitive in price; and suitable for forced drying.
Advantages: excellent corrosion protection; low SHE risk; fast drying and short recoating time; very low VOC; excellent adhesion; high flash point; overcoat able with most coatings; good flexibility; low aerosol formation when spraying; good spray ability; very good water-resistance; and zinc epoxy with high performance.
Advantages: ultimate corrosion protection; environmental efficient; fast drying and short recoating time; no VOC; long pot life; excellent adhesion and water-resistance; excellent abrasion and chemical resistance; high solids; good hardness development; no mud cracking problems; 200[micro]m dft; very good water-resistance; can be used at one-coat HB paint system; zinc content in dry film complies with SSPC 20; and dry heat resistance up to 400[degrees]C.
The real benefits are high performance, cost savings by higher throughput due to shorter drying time/shorter recoating times, lower insurance premium, no expenses for thinners and shorter down time due to fewer coats or odor problems from solvents.
An increasing number of real life case histories and results from severe accelerated testing confirm that waterborne coatings match solventborne equivalents in corrosion protection and even surpass solventborne coatings in performance, waterborne acrylics, epoxies and IOZ alkali silicates are in general faster drying and have shorter recoating times than their solventborne equivalents.
For the vinyl-acrylic primer at 150 and 200[micro]m dft, over coated with the waterborne topcoat, we see that adhesion is good for all recoating times and drying temperatures after seven days of drying/curing (for 5 and 10[degrees]C over coating with topcoat was done after six, 16 and 24 hours).
For the epoxy primer at 150 and 200[micro]m dft, over coated with both topcoats, we see that adhesion is good for all recoating times and drying temperatures 23[degrees]C/40[degrees]C after hours days of drying/curing.
It''s important to protect the worktop before using it again, so only start this job if you have time to apply enough coats of oil (see the manufacturer''s instructions for drying and recoating times
), although if you''re just doing patches of worktop, you could cover them up.
