Instructions For Use

1. Preparation of Elements: Other than normal cleaning procedures, no special preparation is required. The best final cleaner is reagent grade or C.P. acetone.

2. Preparation of Cement: Prepare Type C-59 by the addition of catalyst to cement in a clear glass container. Thorough mixing is important. While stirring, hold container up to the light and observe the Schlieren Effect. When the Schlieren Effect disappears, continue mixing for at least 30 seconds. The entrapped air in the cement will surface if the mixture rests at room temperature for a short time, or is briefly subjected to a vacuum of 625mm Hg. (25" Hg.) The catalyst bottles have a specially designed controlled-drop tip, pre- calibrated at our laboratory to an accuracy of 1%. To use, squeeze the inverted bottle, allowing one drop to fall at a time. For 2:100 mixture, use 2 drops per 3ml. of cement. For 5:100 mixture, use 5 drops per 3ml of cement. (or 8 to 5ml or 40 to 25ml).

N.B. The catalyst bottle supplied with Type C-59 Cement contains more than sufficient catalyst for a 3:100 catalyst:cement ratio.

Safety: Although LENS BOND is quite safe to use, some persons may be sensitive to the chemicals comprising the formulation. For them, the use of finger cots or gloves is recommended. Adequate ventilation should be provided.

3. Application and Curing of Type C-59: Place the prepared LENS BOND on the concave surface, and place the convex surface thereon. Press down firmly and gently until LENS BOND completely wets the matching surfaces. Then, with a slow rotary motion and light pressure, force air bubbles from between the lenses. Excess Cement can be removed with a cloth slightly moistened with alcohol or acetone. (Excess solvent will remove cement from between the cemented components.) After pre-cure, holding devices can be removed and the components carefully cleaned. Before environmental testing, however, the lenses must be fully cured.

Full-cure time is in addition to the pre-cure time. If there is no reason to remove holding devices after pre-cure, components should be cured for the total time (pre-cure plus full-cure). If there is any doubt about cure being achieved, allow components to cure for a longer period of time. The Cement will not overcure. If cure is not achieved in a reasonable amount of time, the catalyst ratio, mixing procedure, and temperature should be checked.

Note: If the elements will undergo hostile environmental tests, allow 48 to 72 hours between full-cure and testing.

TYPE M-62

Because of its 1 hour oven cure at 70C, Type M-62 is used by companies cementing large quantities of optical elements, and with its 4 hour room temperature pre-cure, the use of Type M-62 permits the technician to mix a quantity of cement and bond many elements before the cement starts to gel. This cement is qualified to meet MIL-A-3920.

TYPE RD3-74

Type RD3-74 is a modification of Type F-65 containing a plasticizer. Because most optical cements contract upon curing, they can occasionally set up stresses in thin elements. This stress could either cause bond breakage or lens distortion. Type RD3-74 solves this problem by remaining slightly elastic after curing.

TYPE DC-90

A Hybrid Two-Component UV Sensitive Cement

Summers Optical has developed a hybrid two component ultraviolet sensitive cement that offers offers optical companies some of the benefits of ultraviolet pre-curing while assuring the complete cures, low strain and excellent thermal and chemical resistance of two component optical cements. 

Lens Bond Type DC-90 permits the user to pre-cure the elements in approximately 12 minutes using a low wattage black light and then full cure at room temperature without any additional UV exposure in 48 to 72 hours. The low viscosity, high flow and wetting abilities of Type DC-90 eliminate the problem of working out entrapped air between large lens and optical filters. The longer room temperature full cure permits a very strong mechanical as well as chemical bond to the substrates while the short pre-cure reduces the need for an excessive number of holding devices.

Pre-Cure and full-cure times are dependent on the UV transmission of the element being bonded.

NOTE: Pre-Cure time presupposes at least 70% UV transmission of the elements being bonded. The elements are on a white background and the light source is emitting 15 watts of 365nm light. The elements can be placed in a oven at 70C after pre-curing for 1 hour for full cure, but for best low stress results, room temperature full curing is suggested.

For more information on our ultraviolet curing lamps please see our cementing department supply section of our web site.

For 3:100 mixture, use 3 drops per 3ml. of cement.

N.B. The catalyst bottle supplied with Type DC-90 Cement contains more than sufficient catalyst for a 3:100 catalyst:cement ratio.

Safety: Although LENS BOND is quite safe to use, some persons may be sensitive to the chemicals comprising the formulation. For them, the use of finger cots or gloves is recommended. Adequate ventilation should be provided.

3. Application and Curing of Type DC-90: Place the prepared LENS BOND on the concave surface, and place the convex surface thereon. Press down firmly and gently until LENS BOND completely wets the matching surfaces. Then, with a slow rotary motion and light pressure, force air bubbles from between the lenses. Excess Cement can be removed with a cloth slightly moistened with alcohol or acetone. (Excess solvent will remove cement from between the cemented components.) After pre-curing with an ultraviolet light, holding devices can be removed and the components carefully cleaned. Before environmental testing, however, the lenses must be fully cured.

Full-cure time is in addition to the pre-cure time. If there is any doubt about cure being achieved, allow components to cure for a longer period of time. The Cement will not overcure. If cure is not achieved in a reasonable amount of time, the catalyst ratio, UV transmission of elements, distance of lamp and power of light source should be checked.

Note: If the elements will undergo hostile environmental tests, allow 48 to 72 hours between full-cure and testing.
