Automatic Drawdown Machine
New Gardco Automatic Drawdown Machine, Item No. DP-8301

The Gardco Automatic Drawdown Machine (DP-8301) was designed to draw down sample coatings with a high degree of reproducibility. Manual drawdowns are often inconsistent due to different operators, which can make comparisons between samples difficult or unreliable. Other factors affecting drawdown coatings are the shear rate and the amount of weight being applied on the applicator. With the Gardco Automatic Drawdown Machine the operator can get consistent, precision coating drawdowns every time.

The Gardco Automatic Drawdown Machine can use all different types of applicators— Microm applicators, Bird type, Wire wound rods, etc. There is no need for any special applicators. You can adjust the speed of traversing armature from 1" to 18" per second to suit the particular drawdown to be made. With constant shear rate and weight placed on the applicator you are guaranteed repeatable accurate drawdowns that are not user dependant. There are two programmable presets that the user can program with custom stroke lengths and stroke speeds. The standard working surface is a 12 x 18 inch glass plate. An optional 12 x 18 inch vacuum plate can be used in place of the glass plate to accommodate different size paint charts. Standard 16” OA Lab rods of either 1/2 or 3/8” diameter can be used.

Vacuum Plates

For Use With Wet Film Applicators

Vacuum Plates
Stainless Steel and Black Hard Coat Anodized Aluminum shown above with optional Neoprene Feet

DP-201505 (9x12) & DP-201510 (12x18) - These drawdown vacuum plates are machined from hard aluminum solid stock and finished with black hardcoat anodized that gives a high durability with corrosion resistance that will dramatically increases wear and longevity of the vacuum plate. The top section of the plate has a series of holes. When attached by a hose connection to a vacuum pump or sink aspirator, the vacuum created holds down paper charts during application of wet coatings with any type of film applicator.

Each plate comes complete with a chrome plated brass ball valve with an easy on/off lever handle to enable or disable vacuum, the included brass barbed hose fitting is for a 5/16” hose ID. Neoprene feet kit sold separately.
