Moreover, by enabling a direct-to-metal application, rather than requiring the traditional two-stage application, NeoCryl XK-117 enables energy-saving opportunities of up to 50% during forced drying
The drying can be sped up by forced drying
. Baking the parts in an oven at 120-150 degrees for a couple hours will greatly speed air drying.
The authors explained that this new technology has already been successfully implemented to accelerate formulations at low curing temperatures, and to increase productivity of coatings processes under forced drying
From this figure it is clear that if we want to have an acceptable film formation under forced drying
conditions (approximately 60[degrees]C), the VOC levels of the coating will be unacceptably high.
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
. Disadvantages: complex film formation process; some limitations with regard to climatic conditions; needs six to 24 hours to become water-resistant enough; and does not support high alkalinity before complete drying.
Thus, a primer is applied to the preheated (100-190 [degrees] F) metal part Forced drying
at 190 [degrees] F for 5-15 minutes has also proven to be advantageous.
The water-based adhesive is reported to provide an immediate bond without forced drying
equipment and is available in 5-gal pails and 55-gal drums.
The soft-feel coating is sprayed onto the film and cured by means of forced drying
The heating equipment is capable of controlling temperatures at 21[degrees]C for spraying and 70[degrees]C for forced drying
and a local paint kitchen has been installed to provide spray operators with an area for paint storage and mixing operations.
The latter-features on-line three-stage spray pre-treatment plant which degreases, iron phosphates, and rinses the metal components followed by forced drying
before delivery to the on-line paint facilities.
